Chamberlain BIOS 252 Exam 1 Questions with verified
answers
2 neuroglia in PNS Ans✓✓✓ satellite cells and schwann cells
4 neuroglia of CNS Ans✓✓✓ astrocytes, microglial, ependymal, oligodendrocytes
A band Ans✓✓✓ dark area; extends length of the thick filaments
abdominal muscles Ans✓✓✓ rectus abdominis, external oblique, internal
oblique, transversus abdominis
Acetylcholine (ACh) Ans✓✓✓ A neurotransmitter that enables learning and
memory and also triggers muscle contraction
action potential Ans✓✓✓ a neural impulse; a brief electrical charge that travels
down an axon
long distance signals of axons
aerobic respiration Ans✓✓✓ Respiration that requires oxygen, occurs in
mitochondria
anerobic glycolysis Ans✓✓✓ Rapid breakdown of Carbs, either glycogen or
glucose, occurring without the presence of oxygen.
arachnoid mater Ans✓✓✓ weblike middle layer of the three meninges
,astrocytes Ans✓✓✓ Provide structural and metabolic support for neurons.
axo-axonic synapse Ans✓✓✓ a synapse at which a presynaptic axon terminal
synapses onto the axon terminal of another neuron
axo-dendritic synapse Ans✓✓✓ a synapse at which a presynaptic axon terminal
synapses onto a dendrite of the postsynaptic neuron, either via a dendritic spine
or directly onto the dendrite itself
axo-somatic synapse Ans✓✓✓ A synapse at which a presynaptic axon terminal
synapses onto the cell body (soma) of the postsynaptic neuron.
axon hillock function Ans✓✓✓ Allows impulses to move away from the cell
beta oxidation Ans✓✓✓ fatty acids get broken down into energy
biceps brachii Ans✓✓✓ flexes forearm
biceps femoris Ans✓✓✓ extends thigh and flexes leg
bipennate Ans✓✓✓ Fibers on both sides of tendon
circular muscle Ans✓✓✓ muscle that forms a ring around a body opening
CNS (central nervous system) Ans✓✓✓ brain and spinal cord
, concentric contraction Ans✓✓✓ muscle shortens
Conduction in different axon types Ans✓✓✓ with myelin the nerve conduction is
faster.For example, whereas unmyelinated axon conduction velocities range from
about 0.5 to 10 m/s, myelinated axons can conduct at velocities up to 150 m/s.
Conductivity Ans✓✓✓ The ability of an object to transfer heat or electricity to
another object.
Contractibility Ans✓✓✓ ability to shorten/contract
contractile proteins in muscle Ans✓✓✓ actin and myosin
convergent series Ans✓✓✓ multiple inputs goes into 1 output
creatine kinase Ans✓✓✓ muscle enzyme found in skeletal and cardiac muscle;
elevated blood levels associated with heart attack, muscular dystrophy, and other
skeletal muscle pathologies
creatine phosphate Ans✓✓✓ acts as an energy reserve in muscle tissue
Cross-crawl contraction Ans✓✓✓ opposite muscle contractions
CSF functions Ans✓✓✓ buoyancy, protection, chemical stability
deltoid Ans✓✓✓ shoulder abduction
